Abstract:

This paper described the field measurement of the static and circulating temperature of Yaha 501 deep well in Talimu oil field, and compared the field measurement result with the calculating results by the regular methods. Field measurement study indicated that the estimated bottom hole temperature from logging/regressive formula was not true formation static temperature, and was less than the actual measurement temperature. There was an error above 10℃for circulating temperature between API method/field experience method of Talimu and field measurement, and the error from API method was bigger than that from field experience method. The affection of the well size and circulating rate on the circulating temperature is specially potent.

Key words: Talimu circulating temperature, static temperature, field measurement
